qtbase: replace ${STAGING_DIR_HOST} instead of ${STAGING_EXECPREFIXDIR}

Replacing ${STAGING_EXECPREFIXDIR} with the $$[QT_INSTALL_PREFIX] qmake built-in variable only covers ${STAGING_DIR_HOST}/usr and misses the following additional host paths:
${STAGING_DIR_HOST}/lib
${STAGING_DIR_HOST}

Replace ${STAGING_DIR_HOST} instead with $$[QT_SYSROOT] so that sed replaces all the host paths contained in qconfig.pri instead of only some of them. This avoids host paths being referenced on the SDK host when using the Qt SDK.
